The Bruins are starting to look like the University of Kentucky basketball program: Talented young players come and go in the blink of an eye, honing their skills and then moving on to bigger and better things.

For the Kentucky basketball players, “bigger and better things” means the National Basketball Association.

For the Bruins, it’s every other team in the National Hockey League.

The latest young, talented Bruin who may or may not be playing elsewhere next season — depending on whose tweets you’re reading — is right winger David Pastrnak. The 21-year-old had a sterling 2016-17 season, scoring 34 goals, but it’s the offseason that should worry B’s fans.

As always, it comes down to money. Pastrnak wants more of it. The Bruins, alas, are like the short-armed alligator in the Geico commercial.

The two sides haven’t been able to work out a new deal, leading to speculation Pastrnak could soon be past tense.

My mission today isn’t to break down the B’s depth chart, or give you a Popsicle headache with long, boring lectures about budgets and salary caps. Instead, I’ll simply pose a question: Doesn’t anybody grow old in a Bruins jersey any more?

Put another way, in 30 or 40 years, when aging Bruins alums are dusted off and asked to drop a ceremonial puck, or speak at a charity event or appear with 100-year-old Dale Arnold (still going strong thanks to Awaken 180 Weightloss!) on the NESN pregame program, will there actually be any aging Bruins in our midst?

Yes, it’s looking more and more like Patrice Bergeron is going to be a Bruin for life, even if, at the end of his playing career, he pulls a Raymond Bourque and does a cameo with another team. But no sweat: The B’s could have him sign the symbolic one-day contract, as Vince Wilfork did last week with the Patriots, and we’d all have a group hug.
